EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and zero-phase reactor.
Effective for reduction of air-propagated noise on the input side of the inverter.
The EMC filter is factory-set to disable (OFF).
To enable it, fit the EMC filter ON/OFF connector to the ON position.
The input side zero-phase reactor, built-in the FR-A720-02150(FR-A740-01100) or less inverter, is always valid
regardless of on/off of the EMC filter on/off connector.

The FR-A720-00030 and 00050 are not provided with the EMC filter ON/OFF connector. (The EMC filter is always valid.)
<How to disconnect the connector>
(1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is off, wait for
at least 10 minutes after the power supply has been switched off, and check that there are no residual voltage
using a tester or the like. (Refer to page 6.)
(2) When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or
forcibly pulling the connector with the tab fixed. When installing the connector, also engage the fixing tab securely.
(If it is difficult to disconnect the connector, use a pair of long-nose pliers, etc.)

CAUTION
⋅ Fit the connector to either ON or OFF.
⋅ Enabling (turning on) the EMC filter increases leakage current. (Refer to page 57)
While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.
